Description of the invention (1) Related applications are not federally funded. I have no research on the background of the invention. It is related to several core-based liquid divergence systems, especially regarding-core-based liquid divergence. The system has an angry assembly, and the formation of the core assembly can better control the gasification rate of the liquid t. Many core-based liquid dispersion systems are used in the art to disperse vaporized particles of liquid (or liquid-containing) active substances, such as insect control agents (such as insect repellents, pesticides, and insect growth regulators). Agents), fragrances and deodorants. See, e.g., U.S. Patent Nos. 4,663,315, 4,968,487, 5,095,647, 5,647,053, and 5,909,845.

Basically, one end of a core is partially immersed in a liquid to be dispersed. The liquid is contained in a bottle. The partially impregnated portion of the core absorbed the liquid, and the liquid was then diffused by capillary / wicking to an exposed, unimpregnated portion of the core. The exposed part of the core is locally heated, sometimes by a flame (such as World Patent No. 99/22776), or optionally heated by a ring heater that is arranged around the core (such as US paper 4 This paper size applies to Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page)

Description of the invention (2 --------------—— 7 # ^…: (Please read the notes on the back before filling this page) Lee No. 4,663,315). This causes the liquid to vaporize into the surrounding air. Continued application of heat to exposed portions of the core creates a vaporization / absorption process that continues until the liquid is depleted. A problem with conventional core-based liquid dispersion systems is that the vapor to be dispersed can condense along the inner surface of a casing enclosing the device. This is a particular problem with a long core and can cause liquid to drip out of the bottom of the device. Another problem is the lack of precise control over the rate of application of the combined pesticide, fragrance or other liquid. Some users may want the active substance to have a low concentration in the air (for example, if a user is allergic to a particular active substance). Others may want high concentrations (such as those in areas affected by mosquitoes). A related important issue is the time difference between the activation of the heater and the time to reach an effective air concentration. The heater can be turned off during the day and then turned on when the user returns home. It is best to spread the liquid as soon as the user returns to quickly remove insects from the room and restore a protected state (regardless of the user's preference for the steady state concentration level) . Another important issue is the loss of liquid after vaporization during storage. Another important issue is that some of these systems tend to apply steam along the top and bottom of the core. This can cause the coldest vapor to condense and run back into the enclosure, or flow out along the outside of the container. Another important issue concerns the rate of spread over time. As for a standard core, once the core starts to be activated, the release rate of this paper is in accordance with Chinese National Standard (CNS) A4 (210X297 public love) 537909 A7 ____B7 V. Description of the invention (3) Decreasing. Therefore, it is difficult to choose a core that can evenly disperse an appropriate amount of liquid for some applications. An improved method is to partially close the part of the core exposed to the air with an air-tight outer sleeve. See U.S. Patent Nos. 5,095,647 and 5,909,845. However, these systems slow down the rate of spread thereby increasing the time between activating the device and releasing the desired amount of volatiles. Therefore, there is still a need for improvement of core-based liquid divergence systems and cores used in conjunction with them. SUMMARY OF THE INVENTION In one aspect, the present invention provides a core assembly for use with a core-based liquid divergence system. The core assembly has an elongated core, and an upper end portion of the core has a recess extending downward and opening upward. An outer cover is included on at least a portion surrounding the core. Alternatively, the outer cover may be made of a metal layer, a metal coating, a plastic sleeve, or other thermally conductive or thermally insulating material. When used with electric heaters, the optimal core is made of a porous ceramic material. In another aspect, the present invention provides a core-based liquid divergence system. The system contains a container that can hold a liquid. The liquid is an active liquid selected from the group consisting of insect control agents, fragrances and deodorants. The container basically has an upper opening. A core assembly is partially arranged in the container, and the container also has an extension that extends the paper size to the Chinese National Standard (CNS) A4 (210X29H) -------------- —— (Please read the notes on the back before filling this page), τ. 537909 A7 B7 V. Description of Invention (4) Parts outside the device. The core assembly has an elongated core, and an upper end portion of the core has a recess extending downward and opening upward. The sleeve or outer cover prevents unwanted gasification from the lower part of the core and dissipates heat more evenly along the core. The recess in the core helps to provide a stream of steam that erupts immediately when the device is first heated. According to personal preference, consumers can replace different core assemblies according to different situations. The outer cover may be an insulating material to limit the heat distribution to the core, thereby reducing the spreading rate. The cover can also be a metal, which can transfer heat more efficiently. Therefore, the present invention provides: (a) the core-based liquid divergence system in the above form, wherein the spreading rate can be changed; (b) the core-based liquid divergence system in the above form, wherein the core's thermal conductivity can be Changes; (c) the core-based liquid divergence system described above can reduce gasification from the core during storage; and (d) several cores of the above-mentioned form, which can be distributed when heated initially Out of the active substance. The summary of the present invention is provided above to facilitate understanding of the general nature of the present invention. However, this summary should not be construed as limiting the invention. Instead, the following preferred embodiments, and more importantly, the scope of the accompanying patent application, should be considered. 7 This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page) Order | -Mongol-537909 Description of the invention The first picture is the first embodiment of the present invention Front view; FIG. 2 is a cross-sectional view taken along line 2-2 of the first embodiment; FIG. 3 is a front view of the second embodiment; FIG. 4 is a cross-sectional view taken along line 4_4 of FIG. 3; Figure 5 is a partial front view of the embodiment of Figure 3, but this example has a slightly different core assembly; Figure 6 is a partial perspective view of the third embodiment; Figure 7 is along line 6 of Figure 7 7 is a cross-sectional view; FIG. 8 is a partially exploded front view of the fourth embodiment; and FIG. 9 is a cross-sectional view taken along line 9-9 of FIG. 8.

Alternatively, the outer cover 22 serves as an air-impermeable coating. When preventing or restricting the spread of steam from the core 16 around the core of the overcoat layer 22 ', the total spreading rate would decrease without the recess of the present invention. Particularly suitable materials for this outer coating include plastics, coatings, or solid casings of different forms, including high-density / high-temperature aluminum, aluminum alloys, copper and copper alloys, polyethylene, polypropylene, polyester, and polyterephthalate Esters and polyterephthalates, such as multilayer polymer films. Referring to Fig. 1 and Fig. 2, a first embodiment of an outer cover 22 includes a set of tubes 30 extending substantially from a hole defined in the cover 18 to a first upper end portion 26 of the core 16. The sleeve 30 is preferably composed of a metal or a metal-containing material, which provides 10 537909 A7 _______B7_ on the core 16 V. Description of the invention (8) A uniform heat spreading, thereby speeding up the liquid 14 The speed of thermally activated chemical reactions. Several holes 32 may be provided in the sleeve 30, the holes 32 allowing volatiles to be released along the length of the core 16. Although metal sleeves 30 containing several holes 32 have been shown and described above, the sleeves 30 may also be made of solid metal foil, metal grid or mesh, or use other materials to change the heat that extends along the core. Differences, and / or restricting the spread of the volatiles, and further 'Although it has been shown above that the sleeve 30 extends from the top of the cover 18 to the upper end 26 of the core, the sleeve 30 may also extend above the core 16 The half extends to the full length of the core 16, or extends only a part of the core 16. Referring next to Figures 3, 4 and 5, there is shown a second embodiment of a cover. Here, the outer cover 22 of the core 16 contains a metallized plastic material. As with the metal sleeve 30 described above, an outer cover 22 containing a metallized plastic material can help provide a uniform heat spread around the core and thus speed up the reaction rate of volatiles in the liquid 14: As shown in the figure, the metallized plastic material can extend along the entire length of the core 16. As shown in FIG. 3, the metallizing material may also extend only above the cover 18. For some applications, different materials can be used on the upper part (above the lid 18) and the lower part (below the lid 18) of the core 16. Furthermore, several holes as described in relation to Fig. 1 can also be used with the plastic sleeve. Although the metallized film has been described above, other types of plastic coated paper that are obvious to those skilled in the art can also be used.

(Please read the notes on the back before filling out this page) • Order — 7 S If 'applicable, it will help slow down the delay The heat-dissipating plastic insulation material of the core 16 slows down the reverse use of volatiles in the liquid 14 and thus reduces the spreading rate of the liquid 14. In addition, plastic materials can also be used for the distribution of materials. Insulating or impervious plastics may be suitable, for example, for applications that are sensitive to the volatiles applied, and other conditions that require only a small amount of volatiles. Referring next to Figures 6 and 7, a third embodiment is shown, in which the 盍 22 comprises a coating. Furthermore, the coating may include a thermally conductive material such as, for example, a metallized coating to facilitate the spread of chemicals into the air. In addition, the coating material may include an insulating material to slow down the reaction rate, thereby reducing the spreading rate. As mentioned earlier, the outer coating may also be selected to limit or prevent the volatiles from spreading around the portion of the core 16 enclosed within the outer cover 22. As mentioned earlier, an outer cover 22 including a coating may extend the entire length of the core 16 or a portion of the core 16 and may also include several holes or vents. Furthermore, the coating may only extend up to the upper end 26, or may extend over the end of the core 16. Referring next to Figures 8 and 9, there is shown a sectional view of the core 16 of the present invention. A recess 32 is provided at the upper end portion 26 of the elongated and porous core portion 20 of the core 16, and the recess 32 extends axially into the core portion 20 in a generally downward direction. The recess 32 (and the wall surface adjacent to it) collects the liquid 14 from the container 12 through the core 16 by capillary action, and forms a pool of liquid 14 in the recess 32. As shown in the figure, the depressions in Luohai can be rectangular, include a curved recess, or can be constructed in A4 size (210X297 mm). The paper size is applicable to the Chinese National Standard (CNS) 537909 A7 B7. 5. Description of the invention (10)- ------------------—— (Please read the notes on the back before filling this page) to form any other shape. The recess 32 is sized and dimensioned to hold a predetermined amount of liquid 14, which can be quickly spread after activation. Although it is shown that the core 16 does not have an outer cover 22, it is preferable to encapsulate the core with a metal sleeve 30, plastic film, or paint as described above. In operation, the liquid 14 is drawn into a porous core 20 in a core 16 through a capillary or "wicking" effect. The heater 16 (not shown) is used to heat the core 16 to a predetermined temperature. When the temperature is reached, the volatiles in the liquid 14 are dispersed. Mongolia-In the recess 32 defined at the upper end 26 of the core 16, a pool of liquid 14 can be formed when the heater is in the "off" condition. When the core 16 is heated, the pool liquid 14 can be quickly dissipated, thereby providing a volatile material which can be used, for example, when the core-based liquid dispersion system has been turned off, After a while, a pesticide needs to be used to quickly clean up a room. The recess 32 is also helpful when the core 16 includes an outer cover 22 that can hinder the spread of the volatiles. In this application, the pool liquid 14 in the recess 32 can be used to increase the spreading rate. As described above, the core 16 can be selectively snapped into the container 12. Then, after the core-based liquid dispersion system 10 is activated, a user can measure the dispersion rate from the container 12 and can selectively select a higher or lower dispersion rate as desired. The core 16 replaces the core 16. In an excellent embodiment of the present invention, the porous core 20 is composed of a ceramic with a density of 0.63 grams / cm3, and is far from 13 paper sizes. The Chinese National Standard (CNS) A4 specification (210X297) is applicable. (Mm) 537909 A7 _B7_ 5. Description of the invention (丄 1) The end 26 includes a recess 32. The core 20 may be nested in any of the aforementioned outer covers 22 to provide different ranges of dispersion. A core 16 constructed in this way has been experimentally shown to maintain a relatively constant spreading rate over time during use. The present invention also discloses a method for emitting a volatile liquid, which includes the following steps: firstly providing a core-based liquid dispersion system as previously disclosed, a container of the system containing the liquid to be emitted and suitable for heating to extend A heater on the outer core portion of the container, which is then activated.
